The nominal voltage for the 33664 MN device is 380/480 Vac, what are the voltage limits ?

The listed maximim and minimum voltages for this one device is different when applied at 480 or 380 V. The customer wants to know what the actual minimum "hold" value is is. Is it 70% of 480, or 70% of 380? It cannot be both, since it is the same device. Minimum "hold" value is 70% of 380V Minimum tripping value is 35% of 480V That means this coil operates between 168 and 266V
